Severe storms persisted across the northern and central U.S. today as a low pressure system continued spinning over the Northern Plains.

Flow around this system pulled in more warm and moist air from the Gulf of Mexico, which allowed for showers and thunderstorms to develop across the Upper Midwest and the Ohio River Valley.

Some of these storms turned severe with strong winds, hail and periods of heavy rainfall. Wind gusts over 60 mph were reported in Belmont, Wisconsin, while heaviest precipitation was reported in Prairie Du Chien, Wisconsin with a midday total of 2.85 inches of rain.

The leading edge of this system also reached over the Great Lakes and into the Northeast, where it produced a few scattered sowers over the U.S. and Canadian border. Meanwhile, the back side of this system created a cold front that moved off the Northern Rockies and into the Northern High Plains. Showers and thunderstorms developed along this front with some severe thunderstorm development. Large hail of 2.75 inches in diameter was reported near Powder River, Wyoming.

To the south of these systems, strong winds, dry conditions, and hot temperatures continued for the Four Corners. Thus, fire danger remained high across New Mexico and Colorado. Meanwhile, a frontal boundary lingered over the Southeast, which triggered a few more scattered showers and thunderstorms from Florida through the Carolinas. Severe storms have not developed in these areas.
